Symmetry, direct measurement, and Torgerson's conjecture

Two forms of direct measurement are considered in the article: a strong form in which ratio productions named by number words are interpreted veridically as the numerical ratios they name; and a weak form in which the ratio productions named by number words may have interpretations as ratios that are different from numerical ratios they name. Both forms assume that the responses to instructions to produce ratios are represented numerically by ratios, and thus the word “ratio”—and supposedly the participants concept associated with it—is being “directly” represented. The strong form additionally “directly represents” the number mentioned in the instruction by itself. The article provides an axiomatic theory for the numerical representations produced by both forms. This theory eliminates the need for assuming anything is being “directly represented,” allowing for a purely behavioral approach to ratio production data. It isolates two critical axioms for empirical testing. An measurement-theoretic explanation is provided for the puzzling empirical phenomenon that subjects do not distinguish between ratios and differences in a variety of direct measurement tasks.     

Consultative services in the schools: A model

A model Child Evaluation Center was established in a regular public school to demonstrate alternative methods for providing psychoeducational services. In addition to its service/demonstration function, the center functioned as a psychoeducational field training clinic for the training of school psychologists. The center was successful in encouraging teachers to utilize consultative services, and, in the process, reducing the number of referrals for formal psychological evaluation.     

The word order problem in agrammatism : II. Production

This study demonstrates that agrammatic aphasics have difficulty describing relations that are signified by the order of noun phrases around verbs or prepositions. The word order deficit is found in a Sentence Order Task, in which written words must be arranged linearly to form a sentence, as well as in oral production. Ordering tendencies reflect factors like animacy or potency, rather than the systematic use of syntactic rules. These results point to a fundamental syntactic disorder in agrammatism.     

Feeling and representing: Computational theory and the modularity of affect

In this paper I review some leading developments in the empirical theory of affect. I argue that (1) affect is a distinct perceptual representation governed system, and (2) that there are significant modular factors in affect. The paper concludes with the observation thatfeeler (affective perceptual system) may be a natural kind within cognitive science. The main purpose of the paper is to explore some hitherto unappreciated connections between the theory of affect and the computational theory of mind.     

Predicting effectiveness of bayesian classification systems

A model is presented for evaluating potential effectiveness of a Bayesian classification system using the expected value of the posterior probability for true classifications as an evaluation metric. For a given set of input parameters, the value of this complex metric is predictable from a simply computed row variance metric. Prediction equations are given for several representative sets of input parameters.     

TRACKING THE GENDER PAY GAP: A CASE STUDY

This article provides a short introduction to standard considerations in the formal study of wages and illustrates the use of multiple regression and resampling simulation approaches in a case study of faculty salaries at one university. Multiple regression is especially beneficial where it provides information on strength of association, specific dollar estimates, and the option to identify outliers by gender. Resampling simulation allows for analysis at the department level and is beneficial where distributions depart substantially from normal, particularly where there are unequal error variances. Results indicate that both regression and simulation methods provided evidence of a sizable pay gap associated with gender, even after controlling for rank, academic field, and years of service. The gap occurs in fields traditionally viewed as female as well as science fields with typically lower female representation. Finally, we discuss implications for remediation based on these models.     

The case of Sophie

The analysis of a girl from ages 3 to 5 years old offers a clinical illustration of an alternative theory of change. In this theory the process of change is organized around nodal points of exchange between patient and analyst, designated as “now moments” and “moments of meeting.” In the case presented, these moments were preceded by an intensification of affect and were accompanied by a sense of openness and ambiguity. As often as not they were nonverbal and sometimes did not even involve symbolic representation. The process resulted in a progressively expanded repertoire of ways of being together and ways of doing things together. In a parallel and mutually influencing track, the child was telling me a story that gave meaning to her world, and increased the coherence of her sense of self. © 1998 Michigan Association for Infant Mental Health
